The claimed subject matter provides a system and/or a method for simulating grasping of a virtual object. Virtual 3D objects receive simulated user input forces via a 2D input surface adjacent to them. An exemplary method comprises receiving a user input corresponding to a grasping gesture that includes at least two simulated contacts with the virtual object. The grasping gesture is modeled as a simulation of frictional forces on the virtual object. A simulated physical effect on the virtual object by the frictional forces is determined. At least one microprocessor is used to display a visual image of the virtual object moving according to the simulated physical effect.
